I was looking into new exhausts for my Raptor. I was thinking about this DG RCM II pipe for it. I ride at sea level (on a beach), would I need to jet it at all? If so what jet would you guys recommend? I was thinking around 147.5? Also, what jets should I buy, I don't want a kit, but I see Mikuni mains come in Large and Small, which do I need?
